Question

Question:-

The area of rectangle is 120 metre square and its breadth is 8 m . find the length of the rectangle and perimeter of the rectangle​

Answer 1

Answer:

area of rectangle = 120 cm2

breadth, b = 8 cm

Area = l x b

l x 8 = 120

l = 120/8 = 15 cm

Perimeter = 2 (l+b) = 2(15+8) = 2 x 23 = 46 cm

Length = 15 cm; Perimeter = 46 cm

Answer 2

Given :

• Area of the rectangle = 120m²
• Breadth = 8m

To Find :

• The length of the rectangle

Formula To Be Applied :

We will use the formula ofof rectangle area in the question :

• Area = l×b
• or, Length = Area/Breadth

Solution :

Given, Breadth of rectangle = 8m

Area = 120m²

Hence, length = Area/Breadth

or, Length = 120m²/8m

or, Length = 15m

Hence, Length of Rectangle = 15m

Perimeter = 2(l+b)

or, perimeter = 2(15+8)

or, Perimeter = 2(23)

or, Perimeter = 46 m

Verification :

Let's Check of our answer is correct or not,

Length = 15

Breadth = 8m

Hence, Area = 15m×8m

or, Area = 120m²

Hence, we got our Answer is correct!

Hence Verified!
